Regulation control system, radio communication terminal unit, regulation control method, and radio communication terminal control method

Abstract

To abolish grouping and realize a regulation of the whole terminal at a high accuracy in accordance with an optional regulation rate. A communication regulation state change instruction is output from the timer generator means 23 at a cycle corresponding to the regulation unit time communicated from a radio base-station apparatus 1 to a radio communication terminal unit 2. When the communication regulation state change instruction is output, a communication regulation state is determined in accordance with a result of comparison of the random number generated by the random-number generating means 25 with a predetermined regulation rate. A communication of the radio communication terminal unit is regulated in accordance with the determination. Thus, it is possible to autonomously determine whether the present state is a regulation state in accordance with the clock value of a timer by the terminal unit and change operation states.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a regulation control system, a radio communication terminal unit, a regulation control method, and a radio communication terminal control method and in particular to a regulation control system for regulating communication in radio communication, a radio communication terminal unit for use in the system, a regulation control method and a radio communication terminal control method.[0003]2. Description of the Related Art[0004]Conventionally, one method of regulation control in radio communication has been a grouping. In this grouping method, radio communication terminals are grouped in advance or by means of a unique identifier, and a base station or an access system provides the groups at a constant time interval with information indicating which group is currently regulated for each regulated group to accomplish the regulation. In the grouping method, the contents are determined in adva...

Benefits of technology

[0015]The regulation control system of claim 1 of the present invention is provided with a radio base-station apparatus for communicating the regulation unit time associated with communication regulation and a radio communication terminal unit including a timer generator means for outputting a communication regulation state change instruction at a cycle corresponding to the regulation unit time communicated from the radio base-station apparatus, a random-number generating means for generating a random number and a regulation propriety determining means for determining a communication regulation state in accordance with a result of comparison of a random number generated by the random-number generating means with a predetermined regulation rate when a communication regulation state change instruction is output from the timer generator means, wherein the communication of the apparatus of its own is regulated in accordance with the determination of the regulation propriety determining means. By setting a timer not at the base-station apparatus side but at the terminal unit side, it is possible to autonomously determine whether a regulation state is realized in accordance with a clock value of the timer by the terminal unit and change operation states.

[0020]The radio communication terminal control method of claim 6 of the present invention is a radio communication terminal control method for controlling a radio communication terminal unit in which a regulation unit time associated with a communication regulation is communicated from a radio base-station apparatus, which includes a step of outputting a communication regulation state change instruction at a cycle corresponding to the communicated regulation unit time, a random-number generating step of generating a random number and a regulation propriety determining step of determining a communication regulation state in accordance with a result of comparison of the random number generated in the random-number generating step with a predetermined regulation rate when the communication regulation state change instruction is output, wherein a communication of the radio communication terminal unit is regulated in accordance with the determination in the regulation propriety determining step. By using this control method, it is possible to change operation states by autonomously determining whether a regulation state is realized in accordance with the clock value of a timer by the terminal unit.

[0021]In short, the present invention makes it possible to realize a regulation control method in which a communication state is determined and fairness of a communication opportunity is not lost at an optional and high accuracy of communication regulation. Moreover, as long as a regulation rate is not changed, it is possible to continue regulation in accordance with the regulation rate even if there is not regulation information by communication information and at the same time, increase the number of communication opportunities for one terminal. Furthermore, by abolishing grouping and determining regulation propriety using a random number, it is unnecessary to consider a portion at which it is difficult to change the number of groupings for regulation at the time of design and it is possible to accurately execute regulation as a regulation rate is increased.

[0022]According to the present invention, by abolishing grouping and determining regulation propriety using a random number, it is unnecessary to consider a portion at which it is difficult to change the number of groupings for regulation at the time of design and accurately realize the regulation at the time of high regulation. Moreover, because the regulation information is communicated from a communication channel only when states are changed, a temporal accuracy are optionally realized and particularly it is possible to restrain the fluctuation of the number of communicable times for one terminal at the time of a high regulation rate. As a result, it is possible to perform the whole regulation at high accuracy in accordance with an optional regulation rate. Furthermore, because a regulation state change is exercised by a timer in a radio communication terminal unit, there are advantages that it is unnecessary to communicate the communication information on regulation control in accordance with a change of states and a radio communication band for communicating communication information is not oppressed even if a time interval is shortened.

Problems solved by technology

Moreover, it is impossible to regulate a terminal at an accuracy equal to or higher than the number of divided groups under high congestion.

Furthermore, excessively small divided groups may extend the length of an instruction for communicating the regulation in a communication channel, and because the position of a terminal group to be regulated is uncertain, it is uncertain whether a terminal involved in the terminal group to be regulated is present in the range of a base station or an access system to be controlled, imposing difficulties on achieving a desired regulation rate.

Moreover, in the case of a regulation determining mode by means of random numbers for solving these problems, a probability in which one terminal is available for communication tends to be extremely deteriorated at the time of high congestion.
